GP wasn't implying that every rider should start their own competitor. Juno is an example of a ride hailing company that corrected for low driver wages through market mechanisms.
Starting a business that has a profitable business model is easy. Just go to investors with a reasonable business plan, and you can get funded. There are angel investors in every town, everyone has relatives, etc.
Spoiler: if you're driving for uber, or delivering for uber eats, you are not in the category of population that has:
a) any chance of starting a company
b) any chance of that company succeeding against a giant.
Because you don't have any money. Because Uber pays you like crap.
